Tankless Water Heaters

Tankless Water Heater Installation in LaFayette, GA

Endless hot water with Navien® and Rinnai® installation. Full manufacturer warranty protection as authorized dealers of both brands.

Authorized Navien Dealer Authorized Rinnai Dealer 15-Year Heat Exchanger Warranty

If you’ve ever run out of hot water mid-shower, or waited 10 minutes for the tank to reheat after back-to-back use, you already understand what a tankless water heater solves. Instead of heating and storing 40 to 80 gallons of water around the clock, a tankless system heats water on demand, only when you need it, delivering an unlimited supply at a consistent temperature with no standby heat loss.

Neal’s Heating & Air installs and services Navien and Rinnai tankless water heaters for homes and light commercial spaces throughout LaFayette and North Georgia. We’re authorized dealers for both brands, which means full manufacturer warranty protection, access to the complete product lineup, and installation that meets every factory specification.

The Comparison

Tank vs. Tankless: What Actually Changes

The difference isn’t just convenience. It affects your energy bill, your plumbing footprint, and how much hot water is available during peak household demand.

  Traditional Tank Tankless
Hot water supply Limited to tank size (40-80 gal), runs out Unlimited, heats on demand
Energy use Heats 24/7 whether you use it or not Runs only when hot water is called for
Energy savings Baseline 20-30% lower water heating costs typical
Lifespan 8-12 years 20+ years with annual maintenance
Footprint Large tank (50+ gal) Wall-mounted, about suitcase-sized
Upfront cost Lower Higher, offset by energy savings
Recovery time Slow, wait for reheat Instant, no recovery time

For most North Georgia households, the math on tankless pays off within 3 to 5 years in energy savings alone, and the practical benefit of never running out of hot water adds value that doesn’t show up in the spreadsheet.

Brands We Install

Navien & Rinnai: The Brands We Install

Navien Tankless Water Heaters

Navien is widely regarded as the leading brand in condensing tankless water heater technology. Their NPE series condensing units extract heat from exhaust gases that non-condensing units waste, achieving efficiency ratings up to 0.96 UEF, among the highest available. Navien units also include built-in recirculation capability, which reduces wait time for hot water at fixtures furthest from the unit.

We install and service the full Navien residential lineup. Navien’s customer service and parts availability are consistently strong, and the units are designed with servicing in mind.

Rinnai Tankless Water Heaters

Rinnai has manufactured tankless water heaters longer than any other brand in North America and maintains a well-deserved reputation for reliability and longevity. Their RL and RU series units cover the full range of residential hot water demand, from single-bathroom households to large homes with simultaneous high-demand fixtures. Rinnai’s Wi-Fi-enabled units allow temperature control and monitoring from a smartphone app.

Both brands carry strong manufacturer warranties. Navien and Rinnai both offer 15-year heat exchanger warranties on qualifying residential units. As authorized dealers, we ensure your installation activates the full warranty coverage.

The Process

The Installation Process: What to Expect

A tankless water heater installation is more involved than a tank swap. It typically requires gas line sizing verification, new venting, and in some cases an electrical upgrade for the unit’s control systems. Here’s what we handle.

  • Site assessment: evaluating your current gas service size, existing venting configuration, and hot water demand requirements.
  • Unit selection: sizing the right flow rate for your household’s simultaneous demand.
  • Gas line sizing: tankless units require adequate gas supply; we verify or upgrade the line as needed.
  • Venting: most tankless installations use a concentric vent system through an exterior wall; we handle all penetrations and terminations.
  • Water connections: inlet and outlet connections, pressure relief valve, and condensate drain for condensing units.
  • System commissioning: startup, temperature calibration, and operational testing.
  • Homeowner walkthrough: we show you how to operate and maintain the unit, including the annual descaling process.

Most tankless water heater installations are completed in one day. Permit requirements vary by jurisdiction, we handle permit pulling in all areas we serve.

Common Questions

Frequently Asked Questions: Tankless Water Heaters in LaFayette, GA

How much does a tankless water heater cost in LaFayette, GA? +
Installed cost for a residential tankless water heater typically runs $1,800 to $3,500 depending on the unit size, venting requirements, and whether gas line work is needed. Condensing units cost more upfront but save more on operating costs over time. We provide a firm, itemized quote before any work begins.
How long do tankless water heaters last? +
With annual maintenance, primarily descaling in North Georgia’s moderately hard water, Navien and Rinnai units routinely reach 20 years. Traditional tank water heaters average 8 to 12 years. The longer lifespan is a meaningful part of the total-cost-of-ownership calculation.
Do tankless water heaters work in cold climates? +
Yes. North Georgia winters are well within the operating range of all current residential tankless units. Rinnai and Navien both offer freeze protection built into their units for temperatures down to around 5°F. External pipe runs in unheated spaces should be insulated regardless.
Can a tankless water heater supply the whole house simultaneously? +
Yes, if correctly sized. This is where the flow rate calculation matters, a unit rated for 8.4 gallons per minute can handle two showers and a dishwasher running simultaneously. We size the unit for your household’s actual peak demand, not a generic estimate.
Do tankless water heaters require maintenance? +
Annual descaling is recommended, particularly in areas with moderately hard water. The process takes about 30 to 45 minutes using a descaling solution to flush the heat exchanger. We include tankless water heater maintenance as an add-on to Comfort Club memberships.
Can I get a tax credit or rebate for a tankless water heater? +
High-efficiency gas tankless water heaters may qualify for federal energy efficiency tax credits under current IRS guidelines. Specific credit amounts and eligibility change year to year, consult your tax advisor for current information. Some utility companies also offer rebates for qualified high-efficiency appliances.
Does Neal’s service tankless water heaters they didn’t install? +
Yes. We service all Navien and Rinnai units regardless of who installed them, and we can service most other tankless brands as well. Call us with your unit’s brand and model for availability.
